Answer: 8x/5
Explanation:
Assuming you meant 2X * 4/5, x being a variable X, then the equation is as follows:
2x/1 * 4/5
Remember any value can always be written as over 1, and when multiplying whole numbers by fractions, you first put the whole number over a denominator of 1.
Then multiply the 2x and the 4, and the 1 and 5 (multiplying your numerators and denominators)
You will get 2x*4=8x
and 1*5=5
Then rewrite the fraction accordingly, 8x/5.
